Kāla-vibhāga: The Divisions of Time from Atom to Brahmā, and the Lord Beyond Time
निशावसान आरब्धो लोककल्पोऽनुवर्तते । यावद्दिनं भगवतो मनून् भुञ्जंश्चतुर्दश ॥ २३ ॥
niśāvasāna ārabdho loka-kalpo ’nuvartate yāvad dinaṁ bhagavato manūn bhuñjaṁś catur-daśa
عند انقضاء ليل برهما، يبدأ في نهار برهما خلقُ العوالم من جديد (لوكا-كَلْپا)، ويستمر ما دام نهارُ برهما قائمًا، حيث يتعاقب أربعةَ عشرَ مانو فينعم كلٌّ بمدّته.
At the end of the life of each Manu there are shorter dissolutions also.
This verse states that when Brahmā’s night ends, the process of world-creation begins again and continues throughout Brahmā’s day.
Śukadeva Gosvāmī explains it to Mahārāja Parīkṣit while describing Vedic time cycles; he notes that fourteen Manus preside successively during one day of Brahmā.
It puts personal anxieties in perspective, encouraging detachment, humility, and steadier devotion by remembering the Lord’s governance over immense cycles of time.
